Positioning control

3.4.9 Travel profile generator and setpoints

3−59

EDSVS9332P−EXT DE 2.0

l Traversing profile parameters can be changed via input POS−PARAM−RD even during a

positioning process.

Stop!

For the "Manual jog function with intermediate stop", POS−PARAM−RD has to be set = LOW.

Fig. 3−22 Linear ramps (L profile)

The profile generator works on an optimum time base using the L profile, i.e. the target

position can be reached as quickly as possible with the acceleration and speed selected.

l The acceleration selected is effective immediately when the velocity is changed.

l Default setting: L profile.
